In bobsledding the sports equipment which the athletes also call the Formula One cars of winter sports plays a more important role than in any other type of win ter sport To ensure that the bobsleds remain on track during cornering at up to 150 km h 93 mph they are split into two parts a so called front cowling and a rear cowling that are connected to each other by an articula tion joint and can rotate relative to each other about the longitudinal axis Among the bobsleds used by the Ger man national team are those from FES that are equipped with high performance bearings from Schaeffler For example two tapered roller bearings from Schaeffler with a high static load rating and insensitivity to shocks ensure the strength required in the articulation joint The high rigidity of the bearings and the joint hold the front and rear cowlings in the correct position relative As soon as there is backlash anywhere in the bearing performance is reduced and the bobsled starts losing speed Enrico Zinn responsible for the technical development of bobsleds at FES to each other and prevent deflection caused by the high transverse acceleration which may amount to as much as five times the acceleration due to gravity The most im portant factor however is to minimize bearing lash by using the correct preload for both bearings As soon as there is backlash anywhere in the bearing performance is reduced and the bobsled starts losing speed says En rico Zinn who drives the technical development of bob sleds at FES Schaeffler is also developing very smooth running plain bearings for the steering system This is important to ensure that pilots can feel the steer ing directly explains Zinn This is essential for them to develop the necessary sensitivity and to find the racing line that makes the difference between victory and de feat And when the athletes lift trophies toward the eve ning sky after international competitions Schaeff ler at least had a small part in their success Headed for gold at 150 km h The German four man bobsled with Francesco Friedrich Candy Bauer Martin Grothkopp and Thorsten Margis at 2018 Olympics in Pyeongchang here and now 63
